Quizplus · Accepted Answer

The strength of a correlation is determined by the absolute value of the correlation coefficient. The absolute value of -0.81 is larger than the absolute value of +0.66 and is therefore the stronger correlation. The values of +1.22 and -3.21 are not valid correlation coefficients as they exceed the range of -1 to +1.
